Kid Rock was hospitalized in the UK on Friday. The rapping rocker from Motor City was scheduled to headline the Download Music Festival in Nottingham this weekend when he fell ill with severe stomach cramps. Medics say the musician was dehydrated.

As he was due to come onstage an announcement was made. It said: “We’ve had the curse of Download. Kid Rock is not very well, we’ve had to rush him to hospital in Nottingham. He apologizes to his fans.”
